'The Mio C520's media player is basic (though you get equalizer settings and playlist creation) and as we mentioned earlier, the interface is somewhat confusing and bare-bones.'
'the navigation on the Rino 520 and Rino 530 are similar to the eTrex Vista C units, in that they come with installed base maps of the US, allows for user downloadable detailed maps, it performs auto routing, off route calculation, turn by turn directions with audible alerts, and has the ability to accept these downloads though a USB connection.'
'The Garmin Rino 530 and Garmin Rino 520 is waterproof to IPX7 standards and is WAAS capable.'
